3cx APP working, handheld phone no outgoing voice

[larcits]

Hi to all,

I would like to seek assistance regarding on our issue, while testing on it using 3cx Application(via iOS or Google Play App) it has an outgoing voice, but when we are using our handheld phone (Flyingvoice) there is no voice while using it but the is an incoming voice. We've try to check on our firewall but it seems there is no problem on that since it is working while using on Application. Note that we've also updated our Hotfix. May i know what is the problem?

Thank you in advance.

Seems that some traffic is blocked.
For mobile applications, it's 5090 TCP+UDP and for the web client, it's 10500-10999 UDP, and also TCP for HTTPS port (for both apps). But remember, that all this traffic will be going from the applications to the Phonsystem and then vice versa, and not directly to each other.

Just to confirm sir, even all ports are passed to PBX Status "Firewall" it is still blocked?
see attached image for your reference.

That is the 3CX server-side on incoming communication.
In your case what if the Phonesystem sends audio to the mobile application, is the traffic reaching to the endpoint device?
Did you perform the test we asked for with the 3CX hosted trial key?

Regarding on the 3cx hosted trial, i am asking if i need to setup a new license key(trial) to our current setup. Since our 3cx is installed to server(on-premise) do i need to try the 3cx cloud version? Correct me if i am wrong?

Set up a new trial key and use a 3CX-hosted machine. Then add a few extensions in there and make tests with calls.

Hi Sir, i tried the cloud version and it works fine, i can hear it using a different browser.

Then, i tried our license in same machine but different browser, I can hear my self. but when i tried to call to outside of our network and call a different machine(outside of network) i cannot hear anything.

So i assume of our firewall is the problem, even we whitelisted all the ports.

Thank you for the feedback and yes, indeed, it seems a networking issue there. Now you will need to see more with your network administrator.
